EDWARD MEIER, OF PHOENIXVILLE, PENNSYLVANIA.

' STEAM-BOILER.

Application filed August 6, 1915.

To all whom it may concern:

Be it known that I, EDWARD C. MEIER, a citizen of the United States,residing at Phoenixville, in the county of Chester and State ofPennsylvania, have invented certain new and useful Improvements inSteam- Boilers, of which the following is a specification.

My invention relates to improvements in steam boilers, the object of theinvention being to provide an improved construction and arrangement ofseparate chamber adapted to receive a pre-heater or super-heater, andcontrol the flow of smoke and gases through said chamber, whereby theheat units may be utilized as desired.

. A further object is to provide a steam boiler of the character statedwith an improved construction of partition wall, whereby a chamber maybe formed by an arrangement of tile supported on the water tubes of theboiler, and which tile are self locking, preventing any. possibility ofaccidental displacement.

IVith these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a view in transverse sectionillustrating my improvements in connection with a single unit boiler.Fig. 2 is a view in longitudinal section through the center of Fig. 1,portions of the structure being shown in elevation. Fig. 3 is anenlarged fragmentary view. showing how the bottom of the chamber isformed. Fig. 4 is a similar view showing how the side walls of thechamber are formed. Fig. 5 is a view similar to Fig. 1 illustrating howmy improved chamber may be located between a pair of boiler units. Fig.6 is a view in section on the line 6-6 of Fig. l with parts of thestructure being shown in elevation.

1 represents longitudinally positioned drums supported on box headers 2connected by water tubes 3, and constituting a well known type of steamboiler unit.

In Figs. 1 and 2, I have illustrated a single boiler unit in which anumber of tubes at the center of the headers are omitted, and in placeof such tubes I -.form a heating chamber 4 by my improved arrangement oftile as will be hereinafter explained. The

Specification of Letters Patent.

Patented Nov. 9, 1915.

Serial No. 43,952.

chamber 4 extends throughout the length of .the boiler unit, and the topis formed by ,in'one direction by other water tubes 3 hav ing astaggered relationship to the vertical series of tubes. In other words,the water tubes of the boiler are arranged in series with the tubes ofone series having staggered relationship to the tubes of other series,and the tile 7 rest between a vertical series of tubes and are heldagainst movement in one direction by an adjacent series of tubes asshown clearly in Fig. 4.

The tile 7 are constructed with tongue and groove interlock as shown at8 and 9 in Fig. 4. In other words between each pair of tubes 3 of thevertical series of tubes, I 10- cate two longitudinal series of tile 7,the lower series having a curved bearing surface 10 resting on the tube3 below and the upper series of tile having curved surfaces 11 at theirupper edges bearing against the tubes 3 above. The adjacent faces of thetiles are fiat and smooth as shown at 12, and at such flat'faces thetongue and grooves 8 and 9 are provided as shown.

The tile is of such a thickness that when supported between the tubes,the outer faces of the tiles at their points of juncture will bearagainst adjacent water tubes 3, and prevent, any possibility of theoutward movement of the tile.

As the curved faces 10 and 11 prevent any movement of the tile 7inwardly, and the tongue and groove formations and 9 prevent anyseparation of the interlocking tile, the wall when once made will bepermanent, and there will be "no danger of disconnection except thenormal wear and tear, and tile can be replaced whenever desired.

To position the tile between the boiler tubes, the lower section 7 isfirst placed in position, and then the upper section is moved intoposition longitudinally relative to the first section.

The chamber 4 is provided at one end in its lower wall with an inlet 13,and with an outlet 14 at its top adjacent its opposite end,

The outlet 14 is controlled by dampers 15, and it is to be understoodthat the products of combustion will enter inlet- 13, flow through thechamber l, and escape through the outlet 14 as regulated by the dampers15.

In the chamber 4, I locate a super-heater 16 which of course mayconstitute a preheater if desired, and I would have it understood thathereinafter in referring to this part 16 as a super-heater, that Iintend the same to cover any form of boiler unit, either forpre-heating, super-heating, or generating steam.

In the modification illustrated in Figs. 5 and 6, the chamber +1: islocated between two boiler units, but in other respects is preciselylike the structure above described, and I have used the same referencenumerals to indicate like parts. In this modification, I haveillustrated the super-heater 16 as supported from the top, while in theform shown in Figs. 1 and 2 the super-heater is projected longitudinallyin the chamber ff. It will therefore be noted that with my improvedconstruction I am enabled to pro vide a chamber through which theproducts of combustion are controlled, and therefore I can heat saidchamber to the desired degree for the purpose intended, and can pr0-vide such a chamber without in any way increasing the size of theboiler, but utilizing to the full extent all of the boiler space.

My improved arrangement of tile may also be utilized to form the sidewall of a boiler as shown in Fig. 1, in which view it will be noted thatin addition to the tile 7 and 8, I employ an outer covering of plaster17 and sheet iron 18 to form the outer surface of the wall.

Various slight changes might be made in the general form and arrangementof parts described. without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfliberty to make such changes and alterations as fairly fall within thespirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In combination with a boiler having water tubes therein, of verticaland h0rizontal partitions supported on the boiler tubes and forming achamber, the vertical partitions of said chamber consisting of tilelocated between vertical series of tubes and bearing against theadjacent series of tubes,

substantially as described.

2. The combination with a boiler having horizontal water tubes arrangedin staggered series, partitions forming a chamber, the verticalpartitions of said chamber consisting of tile located between vertical.series of Water tubes, the tile between each pair of water tubescomprising upper and lower sections having tongue and groove interlock,substantially as described.

3. The combination with a boiler having horizontal water tubes arrangedin staggered series, partitions forming a chamber, the verticalpartitions of said chamber consisting of tile located between verticalseries of. water-tubes, the tile between each pair of water tubescomprising upper and lower sections having tongue and groove interlock,said tongue and groove extending longitudinally of the tile at theirmeeting edges, the opposite edges of said tile curved and bearingagainst the vertical series of tubes, substantially as described.

4. The combination with a boiler having horizontal water tubes arrangedin staggered series, partitions forming a chamber, the verticalpartitions of said chamber consisting of tile located between verticalseries of water tubes, the tile between each pair of water tubescomprising upper and lower sections having tongue and groove interlock,said tongue and groove extending long1tudinally of the tile at theirmeeting edges, the opposite edges of saidtile curved and bearing againstthe vertical series of tubes, and said tile at their meeting edgesbearing against tubes of an adjacent series, substantially as described.

5. In a boiler, the combination with water tubes, tile supported by thewater tubes and forming a chamber, a heater located in the chamber, andmeans for controlling the flow of smoke and gases through said chamber,substantially as described.

6. In a boiler, the combination with water tubes, tile supported by thewater tubes and forming a chamber, a heater located in the chamber, saidchamber having an inlet at its lower end, and an outlet at its upperend, and dampers controlling said outlet, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
